On Apple’s public specs page, it says that the new Apple TV includes an A8 chip and that’s about it in terms of the bundled SoC. However, Apple’s developer documentation goes into more detail specifically listing the hardware as having 2 GB RAM (via Steve Troughton-Smith). This means the internals are actually better than the A8 in the iPhone 6 and latest-generation iPod touch, which only have 1 GB of RAM.
